A jealous Bronx mom who sources say poisoned her children with gas and a toxic liquid mixed with their juice, was charged with two counts of murder and will undergo a psychiatric evaluation, police said Saturday.

Lisette Bamenga forced her 5-year-old son and 4-month-old daughter to drink windshield de-icer — and then left her live-in cop boyfriend a taunting note, law enforcement sources said.

“You got what you want,” scrawled Bamenga in the moments before she sealed her Bronx apartment’s windows with tape, turned on the gas and slit her wrists.

She survived with superficial cuts. Her children, Trevor Noel Jr. and Lillian, did not.

Bamenga, who taught at Public School 58 in Carroll Gardens, Brooklyn, frequently fought with her boyfriend Trevor Noel, a cop assigned to the NYPD’s 28th Precinct, over his alleged affair, the sources said.

She believed he got another woman pregnant — and then carried out her sick vengeance, sources said.

Bamenga, 29, was set to be moved from Jacobi Medical Center to Elmhurst General Hospital, where she will undergo a battery of psychiatric tests.

Residents of the couple’s Parkchester building said they were fortunate that the gas-filled apartment did not explode.

“The smell was so strong if anybody would have ignited something we would have been gone,” said neighbor Lynn Hector.

Social workers had never visited the couple’s home, police said.

Autopsy results on the two children are pending, according to the city medical examiner.
